Confinement times has improved faster than mores law for the last 30 years. It really is closer. But many are unsure if ITER is really the best next step. Either way we are stuck with it now. Mite as well follow through.
No its not. You have the wrong impression of large ELE. First of all they produce a shift in the ecology, not total surface destruction. That is why there is still life on earth. Complex life at that. Second they are mostly very localized and only weather/climate effects are global. A 10 year winter is not going to destroy these disks. On top of all that, our current level of technology means we would survive anything as a species that expect in the life of the sun time frames.
Its not the late heavy bombardment anymore and we are not stupid dinosaurs. We can survive long winters and even in the dark for very long times if we needed to.
Flying is about as expensive as skydiving. Its well within reach if you spend that beer money on flying rather than beer. When i was flying with my own money as a teenager it was costing me a few 100 per month for the 3-5 hours of flying time.
The promise of fusion is really low cost energy without limits.
Fusion right does not promise that. Right now it promises massive, expensive unlikely to compete with renewable s. This "breakthrough" is nothing of the sort. They are fusion a few million atoms. They are further away from anything that remotely maters than traditional fusion was 40 years ago. Its has worse performance than the fusors people make for a hobby.
Thing is the amount of power we use is going up, not remaining constant. And its going up exponentially, at like a few % we are talking about using more energy than the sun in a few 1000 years. Even DD fusion won't last long if we don't adopt a more physically realistic economic model. Perpetual growth just does not work. There is a very strong argument to correlate energy use with economic growth and production.
Of course this "invention" is 99.9% bullshit. They like fused a few million *atoms*. 10 fold is not much of an improvement when you consider that they are another 9 orders of magnitude away from anything useful. Compare this to traditional fusion research that has made gains faster than More's law over the last few decades.
Obviously the people who set these limits are not morons...
No the people who set the limits are covering their ass more than making accurate recommendations, because you exceed these recommendations with some forms of medical diagnostics and treatments. Some places the background levels are above "recommended". So why do we live there?
Simply FUD, radiation is scary and so is cancer. People will blame their cancer on the most outlandish things. So you cover your ass. And give stupid recommended levels that are often impractical but ignore natural sources.
Oh and i know a few people in the IAEA, yea plenty of morons. You are promoted for your political abilities. Not scientific ones.
Plenty of the radioactivity from these sorts of pools comes from things that don't bio-accumulate. Of course some mite. But its as always, TFA is light on details.
The magnetic signature from a magnet drops 1/d^3. So you are not going to detect shit without already being on the ship or so close to it that any other sensor would work better.
The army was working on or already has sterling generators where if you can get the hot box hot you have electricity. Wood, dry grass, paper, diesel, animal fat you name it.

If you could get fusion on the desktop. You can make a nuke in a garage. We spend less on fusion than energy subsidies.

I have worked with "ancient" DNA. Its not a good way to preserve data. Not a good way at all.
So don't drop it?

How much reflection do you get at the water/air interface with ELF?
I keep asking myself how they will prevent them from shooting the wrong person..
Its called a friendly kill, or Frag if you will. Been happening a lot longer than we have had robots.
My instructor would strongly disagree. As does the FAA. And the people who have to pay for plane overhauls.

No neutrons. There is a slight amount of neutrons from side reactions, not from the B11+p IIRC
Nothing wrong with that. But if you run the numbers its not enough. We still need alternatives to coal, oil and gas.

No it doesn't. Read the article.

Including engineer's it seems.
The is the RTS game i want to play! Ok not really, but its funny and in fact quite old.
I am talking about gold, and you can't really counterfeit that.
You mite want to look up the history of paper currency.

300 pages of verse.

Not anywhere in that post did i suggest that you shouldn't prepare for nothing idiot.
It can drive through wall man! Through walls!
Tooling for turbines is much harder than for reciprocating engines. Also there is now a massive support base tooling for reciprocating engines.
